Optimal order finite difference approximation of generalized solutions to the biharmonic equation in a cube
Stefan Müller, Florian Schweiger, Endre Süli
We prove an optimal order error bound in the discrete norm for finite difference approximations of the first boundary-value problem for the biharmonic equation in spac…

The maximum of the four-dimensional membrane model
Florian Schweiger
We show that the centred maximum of the four-dimensional membrane model on a box of sidelength converges in distribution. To do so we use a criterion of Ding, Roy and Zeitouni…
